Abstract: The inventions described here apply to the design of the canopy of a small airplane. The geometry of the joint between the canopy and fuselage is such that no water is allowed to enter the cockpit when flying in wet weather. The joint between the canopy and fuselage is not sealed. Small amounts of water can get thru the joint. This is carried away by a gravity operated rain gutter system before it enters any space in the fuselage occupied by people, instruments, or luggage. This design that excludes water from the cockpit also provides guides that allow the canopy to be opened by rolling it forward on three small wheels in a tricycle arrangement. This system for opening the canopy is very simple, cheap, and light weight. The motion of the canopy as it closes allows a very simple, light weight, and exceptionally secure locking mechanism that engages dowel pins between the fuselage and canopy.
